This invention relates to oil well pumps, the primary object of the invention being to provide means to facilitate the removal of the standing valves forming a part of oil pumps, eliminating the necessity of drawing the tubing and the resultant waste of oil and cost of labor in pulling the tubing, when it becomes necessary to repair the standing valve of the pump.

An important object of the invention is to provide a device of this character wherein the working barrel of an oil pump may be dropped to engage the standing valve of the pump to lock the working barrel and standing valve together so that the standing valve may be readily removed from the tubing.

Another object of the invention is to provide means for automatically releasing the standing valve from the working barrel of the pump when the working barrel and standing valve are moved into the well and the standing valve strikes the bottom of the well, thereby permitting the working barrel to operate free of the standing valve.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Referring to the drawings detail, the refereneecha-racter 5: designates the-well tub-l 7 ing of. an oi'l pump in which the workingbar'- relindicated bythe numeral 6', operates. At the lower end of the well tubing 5, is aval've 7 known as the standing valve of an oil pump, the same including a cage orK body ggf portion 8- provided with longitudinal openings 9 and a seat against which the ball' lvalve 10 operates in controlling the passage of Oils through the-valve.v l'

In the presen-t invention, the standing valve, gd is provided with ain extension- 11 that entendisy upwardly from the upper'end of* the valve` body', where it isl provided witlr a transversellyV extended head 12 formed withi'nolined .l surfaces 13'. The headj is pro-vided Wfi-tha g5" downwardly extended portier-114, and an in clined portion 15 extending from the shank tothe outer endofI the head.

At the base of the shank 11 the body por-1 V tion of the standingva'lve'is formed with in- 60"" clined surfaces l-"deiining lockingV sections 16 that are adapted to fit into the notches 17 ofthe cage 18 that is secured to the lower end of the workingl barrel ofthe pump causing a i twisting movement of the working barrel, 05" for purposes to be hereinafter more fully described.

A rectangular opening 19 is formed in the bottom of the cage 18 and is of a length to permit the head 12to pass into the cage. Re- I.

ccsses are formed in the bottom of the cage in such positions that they will receive the extension 14 and inclined portion 15 of the head 12 to lock the working barrel and standingvvalve together.

The operation of the device is as follows:

When it is desired to remove the standing valve to repair it or remove the paraffin therefrom, the working barrel is moved downwardly to contact with the head 12, whereupon the inclined surfaces of the vhead l2 will move over the inclined surfaces of the notches 17 causing the working barrel to rotate bringing the opening 19 into registry with the head 12 whereupon the head 12 moves into the cage 18. The working barrel is now given a quarterturn so that the head l2 will be extended transversely of the opening 19, or to a position as shown by Figure 7 of the drawings, locking the standing valve to the working barrel.

Should it be desired to replace the standing valve, the standing valve is positioned on the working barrel in a manner as shown by Figure 1, and when the standing valve reaches the bottom of the well, movement of the working barrel into engagement with the standing valve will cause the inclined surfaces of the valve to cooperate with the inclined surfaces of the cage 18 resulting in a quarter rotation of the `working barrel to bring the head 12 to a position in alignment with the opening 19, whereupon the working barrel may be elevated and removed, leaving the standing valve in its operative position at the bottom of the well. Theworking barrel may now be operated in the usual and well lmown manner.

I Claml c Y In anoil well pump, a working barrel, a standing valve within the barrel, a shank eX- tending upwardly from the standing valve, a transversely extended head formed integral with the shank, said head having down-V wardly sloping upper side edges, downwardly kextended portions on the head near the shank, and formed along the lower edges Voft' the head, a cage having an elongated opening and having notches formed with inclined l surfaces to accommodate the downwardly eX- tended portions of the head, to prevent rotary movement ofthe cage with respect to the valve when the cage is being lifted, and means for rotating the cage when the cage is dropped on to the standing valve to bring the head into registry with the elongated opening of the cage.

In testimony that I claim the foregoing as my own, I have hereto alixed my signature.
